【 摘 要 】

The article investigates rotor spinning with a liquid layer on the chamber wall during a visco-elastic shaft operation within the framework of two-dimensional model. The outcomes of the mathematical analysis and trial runs on the stated subject-matter are provided. The article considers the influence of external friction forces and external torque on rotor spinning with the liquid auto- balancing device, located around vertical axis. As a result of the study, the dependencies of shaft bending, system disbalance, torque at a preset shaft angular velocity on the ratio of the reduced mass and rotor mass and external friction forces have been specified. In addition, the dependence, allowing calculation of the angular velocity, when the shaft sticking is possible in case of insufficient engine power, has been obtained.
